Fisher™ ET, EAT, and ETR Sliding-Stem Control ValvesFisher ET, EAT, and ETR general-purpose control valves(figures 1, 2, and 3) are used for throttling or on-offcontrol of a wide variety of liquids and gases. All threevalve designs have single ports, balanced valve plugs,and cage guiding. Metal-to-PTFE seating for stringentshutoff requirements is standard in all valves exceptthose with Cavitrol� III cages. Metal-to-metal seatingfor higher temperatures is standard for valves withCavitrol III cages and optional for all other valves.

The temperature limits of ET valves can be extendedabove 232�C (450�F) by using PEEK(PolyEtherEtherKetone) anti-extrusion rings incombination with a spring-loaded PTFE seal. The PEEKanti-extrusion rings expand to close off the clearancegap between the plug and the cage where the PTFEseal may extrude at high temperatures and pressures.The temperature limits are extended to 316�C (600�F)for non-oxidizing service and to 260�C (500�F) foroxidizing service.

The ET product line is available for a wide range ofapplications, including sulfide and chloridestress-cracking environments common to the oil andgas production industries. To discuss availableconstructions, contact your Emerson sales office andinclude the applicable codes and standards requiredfor these environments.

The easy-e™ Valve Family

ET, EAT, and ETR control valves are part of the versatileeasy-e family of Fisher industrial control valves. easy-evalves share the following characteristics:

� Multiple trim material choices

� Interchangeable, restricted-capacity trims andfull-sized trims to match variable process flowdemands

FISHER ET CONTROL VALVEWITH 667 ACTUATOR

W1916-4

� Different cage/plug styles that provide particularflow characteristics for highly-specializedapplications. The standard cage comes in threedifferent flow characteristics: quick-opening, linear,or equal percentage.

� Whisper Trim� I, Whisper Trim III (figure 6), andWhisperFlo� cages (figures 4 and 5) attenuateaerodynamic noise in gaseous service.

� To help eliminate cavitation damage in aproperly-sized valve, a standard-travel, Cavitrol III,one-stage cage (figure 8) and a long-travel, CavitrolIII, two-stage cage are available in the NPS 1through NPS 8 ET control valve.

Features� Compliance with the Clean Air Act— ENVIRO-SEAL™

packing systems (figures 9 and 10) that provide animproved stem seal to help prevent the loss ofprocess fluid are available. These packing systemsfeature PTFE or Graphite ULF packing withlive-loading for reduced packing maintenance.

� PTFE Seating for Long-Lasting ShutoffCapability—Controlled compression of standardseat construction protects PTFE disk between metaldisk seat and disk retainer (figure 1). Only the edgeof the PTFE disk is contacted by the flowstreamduring normal operation. Excellent shutoff ismaintained by a backup ring or spring-loading thatforces the valve plug seal ring against the cage(figure 1).

� Valve Plug Stability— Rugged cage guiding provideshigh valve plug stability, which reduces vibrationand mechanical noise.

� Cost-Effective Operation and MaintenanceEconomy—Increased wear resistance of hardenedstainless steel trim means longer-lasting service.When inspection or maintenance is necessary, thebody can stay in the pipeline during removal of trimparts. Balanced valve plug construction permits useof smaller, lower-cost Fisher actuators. The ETRvalve also permits easy body interior access withouthaving to remove the bonnet or actuator (figure 3).And, trim inventory costs are cut becausedimensional standardization permits use of moststandard easy-e trim parts.

� Compliance with European Standards— Valves areavailable with dimensions specified by EN/DINstandards. See figure 14.

� Sour Service Capability— Unless otherwise noted,references are to NACE MR0175-2002. Optionalmaterials are available to meet NACE MR0103 andNACE MR0175 / ISO 15156. Material requirementsunder these standards vary by edition and year ofissue; the specific standard must be specified.

ENVIRO-SEAL, HIGH-SEALPacking SystemsENVIRO-SEAL and HIGH-SEAL packing systems offerexceptional sealing capabilities. These systems easilyinstall in existing valves or can be purchased with newvalves. These systems help seal the process toconserve valuable process fluid. The long-life andreliability of these systems also reduce maintenancecosts and downtime.

For applications requiring compliance withenvironmental protection regulations, the uniqueENVIRO-SEAL packing system (figure 10) and a uniqueENVIRO-SEAL bellows seal system (figure 9) areoffered. The emission control packing system keepsemission concentrations below the EPA 100 ppmrequirement.

For an excellent stem seal in applications that are notenvironmentally-sensitive, the HIGH-SEAL Graphite

ULF packing system (figure 10) is offered. TheHIGH-SEAL packing system provides improved sealingat pressure/temperature ratings beyond ENVIRO-SEALlimits.

ENVIRO-SEAL packing systems, available with PTFE,Graphite ULF, or duplex packing, and the HIGH-SEALGraphite ULF packing system feature live-loading andunique packing-ring arrangements for long-term,consistent sealing performance.

NOTES:��Use trim 27 instead of trim 29 for nonlubricatingfluids such as superheated steam or dry gasesbetween 149°C (300°F) and 232°C (450°F).��Do not exceed the maximum pressure and temperature for the pressure rating of the body material used,even though the trims shown may have higher capabilities.��Trims 4 and 29 may be used up to 99 bar (1440 psi) with cleandry gas. For process fluids other than clean dry gas,Use trims 4 and 29 only up to 21 bar (300 psi).��Trims 1, 27, and 37H temperature limits can be extendedto 316°C (600°F) for non-oxidizing service or 260°C(500°F) oxidizing service if PEEK anti-extrusion ringsare used with spring-loaded seal rings.��Use trim 37H instead of trim 37 for temperaturesabove 210°C (410°F). Requires anti-extrusion rings and spring-loaded seal rings for temperatures above 232°C (450°F).

1. These in-body process temperatures assume an outside, ambient temperature of 21�C (70�F) and no insulation on the bonnet. When using any packing at low process temperatures, a castextension bonnet may have to be used to prevent packing damage which could result from the formation of valve stem frost. Material selection for trim and other components will also belimiting factors.2. Temperatures above 232�C (450�F) require PEEK anti-extrusion rings and spring-loaded seal ring.

FOR OPTIONAL METAL SEATING WITHALL BODY MATERIALS

Notes:��Use trim 87 instead of trim 85 for nonlubricating fluids such as super-heated steam or dry gases between 149°C (300°F) and 232°C (450°F).��Do not exceed the maximum pressure and temperature for the pressure rating of the body material used, even though the trims shown may have higher capabilities.

��Trim 85 may be used up to 99 bar (1440 psi) with clean dry gas. For process fluids other than clean dry gas, use trim 85 only up to 21 bar (300 psi).��Trim 87 temperature limits can be extended to 316°C (600°F) for non-oxidizing service or 260°C (500°F) for oxidizing service if PEEK anti-extrusion rings are usedwith spring-loaded seal rings.
